PAINT-MIXER.

SPECIFICATION forming part of Letters Patent No. 484,851, dated October25, 1892.

Application filed July 29, 1892- Serial No. 441,566. (No model.)

To all whom it may concern:

Be it known that I, PETER FAUST, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Paint-Mixers; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to devices for mixing liquid or solid substances,and more particularly paint.

This invention consists in the novel construction and combination of theparts hereinafter fully described and claimed.

In the drawings, Figure 1 is alongitudinal section through the tank ofthe mixer. Fig. 2 is an end view of the mixer, showing the drivingmechanism.

A is the mixing-tank, supported on the legs 8 and adapted to receive thematerial to be mixed.

B is a worm-shaft journaled in the bearings b, secured to the ends ofthe tank and having a beveled toothed wheel I) secured on the end of itoutside the tank.

0 is a worm, preferably formed in sections and secured upon the shaft Binside the tank. This worm is madelarge enough to work close against thesemicircular bottom a. of the tank, and the ends 0 of the worm formscrapers, which work close against the ends A of the tank. The worm isalso provided with a series of holes or perforations 0, extendingthrough it. These holes 0 are very small and numerous. They passtransversely through the blade of the worm and are preferablysubstantially parallel with its axis. When the worm is revolved, itpresses the paint in one direction, and the resistance of the paint tocompression causes it to be forced repeatedly through the holes 0 in aseries of small streams, which are repeatedly reunited and resubdividedby the continued motion of the worm and itsperforations,therebyeffecting the homogeneous mixture of the paint. Oneof the bearings b is provided with a stuffing-box B to prevent leakaround the shaft.

D is a faucet forletting the mixed liquid material out of the tank.

Any approved mechanism may be used for driving the worm besides thathereinafter described. The worm is driven for a space of time in onedirection and then its motion is reversed and it is driven in theopposite direction. his change of motion is repeated and the material inthe tank is worked back.

and forth from one end of the tank to the other and is squeezed throughthe holes in the worm until the material has been mixed sufficiently.

E is a driving-shaft journaled in the bearings 6, one of which issecured to the tank and the other carried by the bracket 6', which restson the floor.

F is a beveled toothed pinion secured on the shaft- E and gearing intothe wheel b, which revolves the worm.

G G are belt-pulleys which runloose upon the shaft E, and H is a pulleysecured on the said shaft between the two loose pulleys. The pulley H isdriven from any suitable drivingpulley by the open belt 9 and thecrossed belt g, which run upon the pulleys G and G, respectively, whennot on the pulley H.

I is a belt-shifter for moving the belts. This belt-shifter has itslower ends 71 pivoted to the bars t", which are secured to the bracket6'. The shifting of the belts may be effected by hand; but in order thatthe motion of the worm may be reversed automatically at periodicintervals the fol-lowing mechanism is used. A worm J is secured on thehub of the loose pulley G, andj is a worm-wheel provided with a shaft3'', which runs in a bearing 70, projecting from the bracket e.

M is a lever pivoted in the bracket m, which is secured to the brackete.

N is a connecting-rod pivoted to the top of the lever M and t0 thebelt-shifter I, and n is a connecting-rod pivoted to the lower end ofthe lever M and to the crank-pin n, projecting from the worm-wheel j.

The belts are arranged so that the belt g never entirely leaves theloose pulley G when driving the pulley H, and so acontinuous rotarymotion of the worm J in one direction is effected. The worm J turns theworm-wheel continuously and the motion of the crank pin reciprocates thebelt-shifter. The belts are therefore caused to engage with the pulleyHat periodic intervals and to drive it for a prearranged space of timefirst in one and then in the opposite direction.

\Vhat I claim is- 1. In a mixer, the combination, with a water-tighttank provided with a semicircular bottom, of a worm formed of acontinuous spiral bladeprovided with a series of perforations, anddriving mechanism for revolving the worm in the tank, whereby thematerial is squeezed repeatedly through the said perforations,substantially as set forth.

2. In a mixer, the combination, with a water-tighttank providedwith aseniicircularbottom, of aworm formed of a continuous spiral 1 bladeprovided with a series of perforations,

the periphery and ends of the worm operating to scrape the bottom andends of the tank,
